T all whom ma'y co'ncem:

Be it known that. I, JACOB DAN-aid, a

' citizen of the United States, residing in St;

Paul, in the county of Ramsey andyState of Minnesota, have invented a new and useful Im rovement in Sheet-MetalPails for Lard an other Articles, of which the following is a specification. v

My invention relates to improvements in sheet metal pails for holding and shipping lard and other materials.

The ohjectof my invention is to provide a sheet metal lard ail of a neat,"strong, sim-- ple, 'eflicient and urable construction, capaa the arts together, (which'is necessaryorde Y sira 'le not only for sanitary purposes, but

ble.of being manufactured without soldering also for economy of manufacture,) m which the 0 en mouth of the pail may beof'the.

full ameter. and free from internal shoulders or projectlons, in which-a tight and secure closure may cover and the body of the pail, iii-which the cover'may be read ly opened without danger of cutting or injuring ones fingers, in which snuglyagainst the'bod'y of the ail and be securely united 'thereto, in which the cover will have a central dome or cavity to ace commodate the surplusbulk-oflard in the pail as the cover is forced home, (a feature which. is necessary in lard pails as equal weights of lard vary somewhat in bulk), in

which'the central dome of the cover may be flush or on a level with the rim of the cover I so thatthe pails can be piled or stacked one on top-of another as required, and in which at thesa'me time the empty pails may be conveniently nested together for shipment from the can factory 'to the butcher or packer without causing the nested empty pails to stick or 'wedgefast together or causing the inside. surface'ot one nested pail to scrape against the outside'surface ofan otherifiested pail, and thus mar, scratch or injure the decoration or lithqgraphing on the outside of the pail. i

Myinvention consists in the means I employ to practicallyIaccomplishthis object or result as herein shown and ,described'andj more particularly specified in the claims.

In the accompanying drawing fonning, a part of this speci cation Figure 1 is a central verticallsectmn through the bailears er a sheet metal pail embodying my invention. Fig. 2 isa side eieyation, partly in vertical 'vation partly thereto.

.The body meeting edges seamed or secured'together by a folded or lock seam b; which has an outwardly projecting portion 1) at the upper ormouth end of the body B sothatthe body of the vessel may have a smooth inside friction seat wall at its mouth to tightly fit the external friction seatwall f of thecover, and

a 7 5 B of the-pail or vessel has its anfinternally projecting portion 1) below said externally projecting portion b so that I the outside of the'body B may have a smooth surface or seat b for the bail ear D to fit By providing. the body B of thehus with. an externally projecting" vessellock seam at its upper portion where-thebed coo crates with the cover and with an internally projecting folded or look seam at its portion below where the can body its and cooperates with the bail ear, I am enabled. to

give both the cover and the bail ear a snug portions of the body engagedby each. i .The lock-seam at thelower end the body in a seaming flange or portion 5 of a single lap or thickness suitable for seamingwith the bottom head A,--and this iockside seam b, which b of the body Bterniinates.

throughout its length is of the-customary. four thicknesses, terminates at the upper or mouth end of'the can. body in a seaming flange o-r'portion b of a single lap or thickness, suitable for turnin into a-roll with the seaming flange dot the bail ear D'.

To securely unite the-bail ear D with the body of the pail without the use. of solder rivets or other fastening devices, the bail ear is provided with a seaming flange (1 adapted or roll I) with the seaming flange. b? of the body -B, and with an extended horizontal shoulder d which fits snugly under and it to properly retain its curvature or arch be readily'understood from Fig. 7 of the seamed together.

Each of the bail ears D its-furnished with a raised circular boss d having an eye or opening (Z therein to receive. the hook C tial with the upper part of the raised portion (1 The bail ear is preferably of'ageneral triangular shape with rounded lower end; It is of sufiicient Width or extent. horizontally to give the horizontal bearing shoulder d a length of an inch or such matter so that thearc of the horizontal shoulder al will, in connection with the external 'roll or scam I)? uniting the bail ear to the body, give' the bail earthe requisite stifiness or rigidtty to cause shape corresponding to that of the-body B. against'which it fits, and thus prevent the' bail ear from springing away from the body although the bail ear is only seamed or Tocause the bail ear to more,closely' and snugly-and firmly hug or fit the body B and to prevent the pressure of the seaming tools in the operation of seaming the bail ear Jon the body from causing the lateral edges of the bail ear to tend to spring away from the body, I prefer to make the curvature of the bail ear somewhat sharper than that of the body a ainst which it is to fit,'so that when the bai eari sfseamed to the body, the pressure of drawing the artstogether will cause the side portionof t e bail ear tosnu 'ly hug 0r clamp the body of the vessel. 'ilis will drawing which shows the parts before being The cover F has an external friction seat Wall or flange f, tightly fitting the. corresponding internal friction. seat wall I) at the upper end or mouth of the body so .as to form a tight closure therewith. The cover F is also provided with a raised central dome f plus bulk of the lard or material in the pail when the cover is forced home. This is necessary in lard pails, as a fixed quantity by weight is'required to be in each pail and as the bulk of equal weights of-lard varies to some considerable exterit'owing to various conditions, so that the pails fill with the lard to various extents, a'nd 1n the" ller pails when thecoveris forced home, unless surplusspace is afforded by the dome shape of the cover, the lard will be forced out by. the cover or revent the cover from being snugly and i'hlly'seated or forced home on the body of, the vessel, thus preventing a tight closure.

The dome shaped cover F is provided with a folded horizontallyprojecting rim f ltll tuflling an annular shoulder which firs against the annular shoulder l) onthe body of the vessel and gives a smooth finish to the vessel as a whole and stren thens and reinforces the rim of the cover and provides it with an external projection or shoulder, which, with the shoulder or roll I) on the body of the vessel 'fbrms an annular crevicef" between the rim of the cover and the external shoulder on the bod that enables the friction fit cover to be .rea 'ly removed" by any suitable blade-like tool. The annular rimf of the cover is flush or on a level with the central dome of the cover so that the filled lard pails may be piled or stacked one on top of another, as required for shipment or storage.

To enable the empty pails to be properly nested together for shipment from the can ffactory'to the butcher or packer, the bail ears are so located in relation to the conical or taperinggbodies of the vessels so that the lower portion of the bail ear bosson each pail Will act as a stop shoulder byengagement with the annular roll I) of the pail Within which it is nested to limit the extent to which.

the pails can nest or telescope together, and

b of the inner pail from scraping against the inner surface of the pail within which it is inner surface of the pail. within which it is nested, and thus prevent marring or injuring of the lithographing or decoration b of the pails. This is .a matter of considerable importance, as lard P31188116 ordinarily lithographed on theouter surfaces of the bodies.

The bosses of the bail ears, by limiting the extent to which the em ty pails can nest to-v gether, also prevents t em from becoming stuck or wedged together so that they cannot readily be removed out injury.

The bearing shoulder d at the upper portion of the bailear D forms a supplemental eye boss d. .The face d of the su plemental boss (1 like the bearing shoulder 1 is preferably curved to conform to the curvature of the ail body B upon. whichthe bail eantits. As t e bail ear is made of a slightly-sharper curvature-than the body, the o eration of seaming the bail ear on the b0 y puts the bail ear under a clamping tension and causes its side flanges (Z tov snugly hug or clamp the curved surface "of the body B.
